SSG-menu.js

Overview

The SSG-menu.js file defines two primary routes for a static site generator (SSG) management system:

Authentication Routes (/auth): Handles user authentication to secure access to the SSG menu.
SSR Menu Routes (/ssr-menu): Facilitates listing website pages and regenerating them via server-side rendering (SSR).

These routes ensure controlled and secure access to SSG tools, while enabling efficient page management.
